Throttle Body Improvements: 986 e-gas

[Topless]

There is a pretty good book on this subject written by Jeff Harmon. He has done more engine hot rodding over the years than anyone I know. It is not the final word on this but it is well written, reasonably current, and does a good job of showing you how to make more power with any engine platform while dispelling the engine mod myths floating around on the internet these days. This is a useful reference for anyone interested in hot rodding or power mods. It gives you the knowledge to separate true performance improvements from marketing hype. Worth a look.
